Okay, with Singapore Airlines announcing cancellation of BOTH of the world's longest scheduled flights, it's time for a new and "official" ranking of the ten longest. This topic has been done to death on this site, but this is a substantial change/shake-up.

Below is the list I've got. Can anybody clarify?

Here's the criteria, so there should not be any controversy:

-- Nautical miles (flight times are too fickle) according to the Great Circle Mapper http://gc.kls2.com

Just nitpicking a little but ATL-JNB is the longest route that is nonstop in both directions. Doesn't affect your ranking based on your guidelines but just wanted to specify that the westbound DFW-SYD makes a scheduled stop in BNE.

Disappointing SQ can't keep up their long routes. Hopefully they'll be back at some point in the future.

Quoting Viscount724 (Reply 4):Since you're including SYD-DFW which only operates in one direction, you should also include DFW-BNE (7215 nm) which also only operates in one direction. I believe it then becomes 4th longest.

Yeah, that'd be correct, but I hate doing it, seeing that it's technically part of QF's SYD-DFW service. Very annoying!
